Undeleting events in Google CalendarIf you accidentally deleted one or more events in Google Calendar, you can use this program here to undelete them. Google Calendar does not really delete events, the events are just marked as deleted. This is necessary so that programs that sync with Google Calendar can be informed which events have been deleted. The program here can display these deleted events and allows you to undelete them.
To start the program just download it and double click it:
GCTool (Mac Download, Windows/Linux Download).
On Windows/Linux you need to have Java installed. If you don’t have Java, install it from http://www.java.com.
After starting it you first have to sign in and allow the program to access your calendar:
Then you should see the window below. Select a calendar, click on "Load recently deleted events", select one or more events to undelete and undelete them by clicking on "Undelete selected events". You can select multiple events by selecting the first one and clicking on the last one while holding SHIFT (to select that range of events).
After a few seconds the selected events should vanish from the list because they are no longer deleted. Now click “Refresh” in Google Calendar or reload the website in your browser to see the undeleted events:
